Soil respiration, soil carbon, soil temperature, and soil moisture measured in urban green spaces in Helsinki during 2020-2022

Dataset associated with Karvinen et al. (2024) article entitled "Soil respiration across a variety of tree-covered urban green spaces in Helsinki, Finland". Soil respiration CO2 flux, soil temperature, and soil moisture were measured during the growing season (May-September) in 2020-2022 at four measurement sites encompassing a variety of urban green space types commonly found in the city: a small urban forest (Forest), a managed park (Park), road verge between a roadway and a sidewalk (Streetside), and a fruit orchard (Orchard). Soil samples were collected from all measurement sites during the campaign years to determine soil density as well as soil organic carbon (SOC) and nitrogen (SON) content and stock.
